Frequently asked questions
- What integration techniques are tested in O Level AMath?
- Power rule, integration of standard functions (sin, cos, eˣ), definite integrals for area, and simple substitution. Know how to find the constant of integration for indefinite integrals.
- How do I find the area under a curve?
- Sketch the curve, identify limits, set up ∫ f(x) dx between those limits, integrate, then substitute the upper and lower bounds. Check if the region is above or below the x-axis.
- What are common O Level integration mistakes?
